// 6.1.2 Distribution of authentication data from HSS to serving network
//------------------------------------------------------------------------------
/* NOTE 2: It is recommended that the MME fetch only one EPS authentication vector at a time as the need to perform
 * AKA runs has been reduced in EPS through the use of a more elaborate key hierarchy. In particular,
 * service requests can be authenticated using a stored K ASME without the need to perform AKA.
 * Furthermore, the sequence number management schemes in TS 33.102, Annex C [4], designed to avoid
 * re-synchronisation problems caused by interleaving use of batches of authentication vectors, are only
 * optional. Re-synchronisation problems in EPS can be avoided, independently of the sequence number
 * management scheme, by immediately using an authentication vector retrieved from the HSS in an
 * authentication procedure between UE and MME.
